I love how this video did not need any clickbaity title or whatever to pull someone in. The topic in itself is enough to spike curiosity. And honestly that is valuable
@
Amazing research by Prof. Álvaro Romero-Calvo, Theo St. Francis, and team!
@
I had to watch this twice. The first time to appreciate the visuals, and the second time to take in the science! I love how funky and human this art style is.
@
As always, an interesting topic explained in an engaging and entertaining way.

But the music was really loud; it pulled me out of the enjoyment and annoyed me.
@
The engineering is impressive, but what stood out to me is the mindset behind it.

In space, you don't build systems that work only when conditions are ideal, you build systems that keep working when failure isn't an option.

That's a principle worth applying far beyond engineering
@
The music is not distracting at all
@
Love the video but the music is too loud! It's distracting
@
Did you intend to make the astronauts as unsettling as possible
@
Those long-limbed astronauts are freaky looking 😊

Hi crew mates!
@
I love learning
@
I never even considered the fact that excess carbon dioxide needed to be disposed of,
@
I don't think most people realize how important air is when we talk about space travel. When we watch science fiction or space fiction movies, we usually wonder why it hasn't happened yet, why haven't we reached Mars or other galaxies? It turns out there's so much to think about... while we live on this planet that provides everything for us, we tend to always complain and hurt the planet... we're like spoiled passengers.
@
Dope vid but the music was a bit too loud making it a lil difficult to hear the speaker.
@
Meanwhile, I forget to water a plant. 😭

Anyone who's played amongus knows when O2 has been sabotaged you just have to type the code and you're good to go
